Background The continuous increase of the automobile conservation amount causes a series of problems of climate change, air pollution and the like, and the development of new energy automobiles is a strategic measure for coping with the climate change and promoting green development. Related researches show that about 86% of urban population lives in areas with PM2.5 concentration exceeding the standard, about 180 ten thousand people die in one year, and the problem of environmental pollution is not sustained. In recent years, the construction of charging infrastructures in China rapidly develops, and the charging infrastructure network with the largest quantity and the widest distribution in the world is built. At present, however, the public charging facilities in China have smaller occupation ratio, and part of public charging facilities have the problem of low use efficiency, meanwhile, the site selection construction of the charging facilities cannot meet the green development requirement, the charging facilities cannot better guide travelers to select new energy automobiles, and the atmospheric pollution degree is not effectively relieved, so that the site selection and allocation construction of the charging facilities are particularly important. Compared with the prior art, the method comprises the following steps: In comparison with the technology of patent CN 113888044A' a method for selecting the site of the charging pile by considering the carbon emission of the motor vehicle 1.
